SASH-FASTENER.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed January 28, 1921.` Serial No. 440,575.

To all whom 1f/may concern.'

Be it known that I, CYRUs H. LoUTREL, a citizen of the United States, residing at South Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sash-F asteners; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same.

This invention relates to certain new and useful improvements in a sash fastener, especially of that type commonly employed for railroad and other car windows.

The principal object is to greatly simplify the construction and thereby cheapen its manufacture and produce a better and more practical device which can be readily mounted on the sash frame in an expeditious manner.

The invention further resides in and consists of the specific structural features hereinafter described and claimed, reference being made to the accompanying drawing wherein:

Figure 1 is an inside elevation of the preferred construction of my improved sash fastener;

Fig. 2 is an irregular section thereof on line 2-2 of Fig. 1;

Fig. 3 is a detail fragmentary section showing a modified form of hollow post, and

Fig. 4 is a view similar to Fig. 2 but showing another modification both as to the hollow post and the manner of securing the fastener to the sash.

This applicationis a continuation in part of my pending application Serial No. 386,313, filed June 3, `1920, and allowed January 8, 1921, and is intended to better portray and describe the invention in its commercial form.

Referring more in particular to Figs. 1 and 2 of the drawing, the numeral 1 designates the casing which is substantially rectangular in shape and open at its back, the said open back being provided at its corners with dowel pins 2 designed to engage in re* cesses in the sash frame 3, or to be forced therein, to aid in firmly anchoring the casing in place. A rigid finger hold or rest 4 extends integrally from the casing and un derlying the finger is a fastener-operating lever or handle 5 constituting one arm of a bell crank of which the other arm 6 forms the fastener member. The fastener member 1s secured in position on the casing by a hollow post 7 preferably integral with the casing and interiorly threaded. The fastener operating lever extends through an opening S in the side wall 9 of the casing and confined between this wall and the opposing inner face of the fastener arm is a coiled spring 10 the function of which is to urge the fastener arm toward operative position.

In mounting the fastener on a sash, the lugs or dowels 2 are inserted in their seats in the sash, and a threaded bolt 11 passed through the sash and driven firmly within the hollow post.

With reference to this fastening operation in detail, the threaded bolt has a head on its outer end which is either slotted for convenient operation by a screw driver, or this head may have any suitable wrench-hold; a slight mortise is preferably cut in the sash and a washer 12 placed therein, and the bolt is passed through the washer and sash and is driven into the threaded post, sothat when the head of the bolt is impinged against the washer the casing will have been securely fastened to the sash.

The edges of the sides of the casing as well as the edge of the hollow post are extended slightly beyond the fastener lever, so that when the casing is secured to the sash there will be no binding between the latter and the fastener lever.

In the construction shown at Fig. 2, the hollow post is made integral with the casing, but while this construction is preferred, nevertheless this post element could be driven firmly from the outside into the casing and made rigid therewith in any suitable manner such as by sweating or the provision of interengaging serrations, which are very ordinary mechanical expedients, a construction of this sort being shown at Fig. 3, the separate post being designated by the numeral 13 this post being provided with a head 14 which is in close contact with the outer surface of the casing.

In both styles of post, as shown at Figs. 2 and 3, there is no opening extending out through the face of the casing, and the operation of fastening to the sash is precisely the same in bothinstances.

Y bolt 16 is passed through the thimble from j Referringito Fig; il, theihollow post element is provided for by expanding the outer edge of a hollow thimble 15 over onto a conical seat formed in the outer face of the casing, the latter, of course, being perforated to accommodate this thimble, it being` immaterial in this instance whether the hollow thimble is rigidrwith the casing or not. The fastener operating lever is mounted around the thimble as heretofore described, and in fastening the casing to the sash a threaded the outside into the sash and is engaged by means of any suitable nut 17 mortised in the outer face of the sash, the bolt being headed so as to fit snugly within the thimble, and either the bolt or nut or both being so constructed as to receive any suitable tool for the purpose of driving the nut on the bolt.

The manner of fastening, however,- is a minor matter, but the construction shown at Fig. 2 is much preferred because it leaves a plain unbroken finish on the outer face of the casing.

n prior constructions employing outstanding flanges with fastening screws passed therethrough into the sash frame, invariably one or more of the screws would be come loosened by constant usage and the fastener would tilt and frequently stick and this required constant tightening of the screws. lt has .also been customary to mortise the flanges in the casing.

n the improved construction the dowels 2 hold the fastener exceedingly steady while all the fastening is done by a single screw which prevents loosening of the casing.

The presentconstruction eliminates the back plate and its post, together with the incidental and special treatment of the post. rlhe casing and its dowels are either made by die castingor they can be pressed up into shape.

l claim: Y

1. ln a sash fastener, a casing having a front plate and side walls and an open back, a dowel pin at each end of each side wall, a hollow post extending from the inner face of the casing, a perforated fastener member pivoted aroundA said post, one of the end walls being extended to forma finger grip, and a fastening member passed through the sash and engaging the latter and the post and serving as a means of positive securement of the casing to the sash.

being extended to form a linger grip, and

a threaded bolt passed through the sash and driven within said post, whereby the casing may be held firmly to the sash with the bolt serving as the means of positive securement.

`3. ln ,a sash fastener, a casing having an open baclr and dowel pins atfeach of its corners, a hollow interiorly threaded post rigid with the casing and extending within the latter, a fastener member pivoted around said post and located between the .dowel pins, the walls of the casing and the post being formed to hold theY fastener member spaced 'from the sash, and a threaded bolt passed through the casing and engaging the threads in the post and serving as themeans to secure the casing firmly to the sash.

d. In a sash fastener, a casing, dowel pins on the rear of the casing, a hollowinteriorly threaded post rigid with the casing and interior thereof, .a fastener member pivoted around said post, anda securing element eX- tending into the post to hold the casing firmly against the sash, i

5. ln a sash fastener, a casing, spaced dowel projections on therear of the casing, a pivoted fastener memberlocated in the space between the projections, a hollow post eX- tending from the casing, and a threaded bolt extending into the post to hold the casing firmly against the sash, 'said casing having an open back and the post being of such length relative to the thickness of the fiastener member that the latter 'is held spaced from the sash.

6. ln a sash fastener, a`casing, spaced dowel projections on the rear of the casing,

a. hollow post extending from the casing, a threaded bolt extending into the post to hold the casing firmly against the sash, and a fastener member located in the space between the projections and having a pivotal Y support carried by the casing.
